The issue is my truck is the SAME generation truck as the 2007-2010 trucks. Which means I too have the design flaw as well but Toyota is refusing to fix their mistakes.

The failure mileage was approximately 165,000.”
“Well known issue with V8 Air intake pump and assembly causes truck to go into limp mode. Very dangerous in Atlanta traffic. Toyota enhanced warranty but did not recall. My repair was $3000 as I was 3 weeks out of warranty.”
